Be safe, rebase! Why should you never merge a branch that's not rebased onto master? #ci #git #vcs blog.tomasfejfar.cz/git-reba…

With Codex, @asana finished a frontend test migration from Enzyme to React Testing Library in two calendar weeks—a project expected to take five more years. openai.com/index/asana/

Hey @1Password I thought that "op" is intended to use to securely access secrets via agents, but IIUC it unlocks the whole account 😱 In my book that's worse for security than putting the secrets to temp files for agents 😢

It's not red.
Ferrari has just officially unveiled its first ever all-electric car, called the Ferrari Luce. • Starting price: $640,000 • Interior co-designed with Apple's former head of design, Jony Ive • Range: 280 miles (expected EPA) • Peak charging speed: 350kW • 122 kWh battery • 1,050 horsepower • 0-60mph: 2.4s • 800v • Four-door four-seater • Four electric motors • OLED screens • Weight: 4,982 lbs • Front motors spin to 30,000 rpm, rears hit 25,500 rpm • Car uses an accelerometer to capture real vibrations from the electric motors & rear chassis. An algorithm filters out unpleasant frequencies and amplifies only the more “musical” sounds. This can be heard inside and outside the car. • Paddle shifter on steering wheel changes how aggressively torque is delivered, with five different levels • The trunk has 21.1 cubic feet of space, the largest luggage capacity the company has ever offered • 197.6 inches long, about as long as a Tesla Model S U.S. deliveries start in Q2 2027.

My /add-task makes the agent add task and immediately continue it's work. @bcherny, did you consider adding an interface to tasks directly, so I don't have to go through chat and risk the agent being distracted?

BTW: Here is my /add-task command: "Add the following as a pending task using TaskCreate, then immediately continue with your current work without switching context: $ARGUMENTS"

Proč myslíte že v ČR má všechno otevřeno 8-17? Podle mě ekonomika o hodně přichází tím, že jsou všichni v jeden čas v práci a pak chtějí všichni naráz volno. Ve Španělsku mají otvírací doby rozházené během dne a přijde mi to logické a lepší.

Hey @mattpocockuk, the /grill-me skill is unbelievably effective relative to the actual prompt length 🤯Essentially the single sentence makes the agent do what usually needs page long skill. Kudos!

Run /insights in #Claude Code. It generated some actionable suggestions for me, and flagged problems I’d quietly normalized, like the agent getting confused about the current working directory in a monorepo.

Ultimate productivity. LLM super friendly as a bonus
We built Things, Notion, Todoist... And this person said "nah, txt file is fine" Unironically brilliant. jeffhuang.com/productivity_t…

Another reminder that writing about what feels like an obvious thing for you still makes sense. Someone is walking the same road you did in the past and may benefit from it. I remember the discussion in @Shopio years ago about this exact thing.
Nobody talks about how URL design impacts your entire architecture. This is not the usual 'use hyphens not underscores' stuff. I mean how choosing /product-name over /product/product-name shaped our caching strategy, backend load, and why our infrastructure costs were 40% higher than projected. Wrote about it: alfy.blog/2025/10/16/hidden-…

Let's try also @cramforce who's collaborator for the package on npm

TFW you spent half a day debugging why your module loading in your updated Docker build doesn't work the way it absolutely should... and you just barely don't know enough to not question anything else then your ability. github.com/vercel/resumable-…
